I think this is really just an icon request question. The save icon question worked well because it came at the issue from the other direction - "Is this icon still appropriate". It wasn't asking for alternatives but was about the specific icon itself. Your question is really just requesting a suggestion for an icon. Can you clarify what it is you want an answer to provide you with?

I don't need an icon but the idea for an icon. An idea that is easily associable with the concept of real time or live data.
